GLENDALE, Ariz. — It went nearly unnoticed in 2013 that Dodgers closer Kenley Jansen pitched more innings, and appeared in more games, than in any season of his brief pitching career.

Jansen has barely been a full-time pitcher for four years. He converted from catcher as a minor-leaguer in 2009. Yet in 2013, Jansen tied for eighth in the majors in appearances (75) and ranked 11th in innings pitched (76 2/3). He didn’t fade down the stretch and had enough left in the tank to make six postseason appearances.

At one point in July and August, Jansen appeared in 11 games in four cities over a span of 17 days.

“I didn’t feel tired at all,” he said. “They held me back in St. Louis but I was ready to go.”

Looking only at the raw numbers, Jansen’s workload might be cause for concern. It isn’t, because the 26-year-old closer seems every bit as durable as his solid 6-foot-5 frame suggests.

“Last year, I didn’t feel fatigued at all,” he said. “I feel good.”

About his weight: Jansen said he recently weighed in “a few pounds” above his listed weight of 260 from a year ago. The Dodgers’ media guide lists Jansen at 257 pounds.

The pitcher said he isn’t on a diet anymore. That wasn’t the case a year ago, when he was recovering from ablation surgery to correct an irregular heartbeat. Jansen said his body-fat percentage is lower these days, though that wasn’t his goal over the winter.

Jansen was reminded Thursday of the incomparable 1974 season by Dodgers reliever Mike Marshall. At age 31, Marshall made 106 relief appearances and pitched 208 1/3 innings out of the bullpen, winning the National League Cy Young Award.

Since the Dodgers signed Jansen to a 1-year, $4.3 million contract on Tuesday — thereby avoiding arbitration — they probably won’t give Jansen the chance to touch Marshall’s standard for durability. Teams tend to protect their closers from overuse.

Maybe Jansen does have 208 innings in his right shoulder, but even he doesn’t want to find out.

“His shoulder must be bugging him by now,” Jansen said of Marshall.

No timetable for Kemp

Dodgers manager Don Mattingly was asked Thursday to outline Matt Kemp‘s timetable for recovery from surgery on his left ankle last October. It’s one of the most burning questions in camp: When will Kemp, who hasn’t been cleared to run since the surgery, be able to resume full baseball activities?

“There’s really no true schedule, I think, with Matt other than when the ankle’s healed he gets to do more,” Mattingly said. “He’s able to hit. He’s hitting off the tee. He’s going to be able to do a lot of things. But included in those things is not going to be running outside. That’s a pretty important part of what he does. Until that ankle lets us know that he can move forward, you can’t really do a whole lot different.”

Kemp has been able to lift weights normally with his upper body, something he wasn’t able to do all last year while he dealt with a surgically repaired left shoulder. That’s been reflected in Kemp’s “free, confident” swings in the batting cage, Mattingly said. There is some optimism early in camp that Kemp’s power could return to its 2009-12 levels, when he averaged 29 home runs a season.

But “until the doctors tell us that (Kemp’s ankle) is totally healed,” Mattingly said, “we don’t really have a schedule for him.”

Mattingly called the Dodgers’ search for a second baseman “probably the biggest thing we’re looking to find out” in spring training. Converted shortstop Alex Guerrero is the front-runner, but Mattingly said he’s in no rush to appoint an everyday starter. “There’s too many questions. … I want to see what we’ve got first.” … All the Dodgers’ position players are expected to be in attendance for the first full-team workout Friday. … Right-hander Josh Beckett is taking an extra day between bullpen sessions, but is otherwise on a normal starter’s schedule so far. Beckett only pitched eight games last year before thoracic outlet syndrome in his right shoulder ended his season. .. The retired numbers at Dodger Stadium will move from above the bleachers to the left-field club level this season, the team announced. … The Dodgers signed 18-year-old international outfield prospect Carlos Mosquera from Panama City, Panama.
